DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
Ensure that the system is voltage-free before installing the device.
•
Ensure that the system is secured and cannot be reactivated by other
persons.
•
Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical
engineering regulations.
For the electrical connection, you must differentiate between a connection
component and an operating component.

The following descriptions apply to standard systems and are limited to the
necessary user-provided connections.
1.
Disconnect the system from the power source and secure it against
unintentional reactivation.
2.
Remove the covers.
DANGER Risk of serious injury or death due to electric shock. Some
parts of the device's circuit board may still be live with 230 V even after the
device has been physically isolated from the power supply by pulling out of
the mains plug. Before you remove the covers, completely isolate the
device controller from the power supply. Verify that the main circuit board
is voltage-free.
3.
Insert a suitable screwed cable gland for the cable bushing at the rear of
the connection component. M16 or M20, for example.
4.
Thread all cables to be connected through the cable glands.
5.
Connect all cables as shown in the terminal diagrams.
